To all whom it may concern:

Be it known that we, ALFRED SEELEY, machine maker, a subject of the Kingof the United Kingdom of Great Britain, and resident of 54 Syke road,Rochdale, in the county of Lancaster, England, and HERBERTl-lonr,'niacliine maker, a subject of the King of the United Kingdom ofGreat Britain and Ireland, and resident of Shaw Hill, Cronkeyshaw,Rochdale, in the county of Lancaster, England, have invented new anduseful improvements in Machinery for Winding Yarns or Threads OntoBobbins or the Like, of which the following is a speciiication.

This invention of improvements in machinery for winding yarns or threadson to bobbins or the like consists in improvements intended speciallyfor and making it much more easy and convenient than it has hithertobeen for yarns or threads, especially yarns or threads which have beenalready wound two or more together or into the form of warps or l1keassemblages or other yarns or threads to be wound singly or two or moretogetheron to bobbins or the like into forms cylindrical or nearly so atone end and tapering at the other so that they may be unwound by beingpulled off the ends of such bobbins or the like.

Although specially intended'for facilitating the winding into such formsas aforesaid of yarns or threads such as those hereinbefore mentioned,the improvements constituting this invention are also applicable forwinding yarns or threads of any other kind into such forms as aforesaidand may also when desirable be put out of action so that yarns orthreads may be wound into cylindrical or approximately cylindricalforms.

Briefly stated, this invention comprises principally the provision inwinding machines of spindles in suitable number and suitably supportedand of such construction as to allow the bobbins or the like to slip orrevolve more slowly than the spindles and in particular spindles such asare described in the specification of the Letters Patent granted to tieabove named Alfred Seeley and Herbert Holt, Number 996,530, dated June27th 1911 and driven by suitable means, drawing-off rollers to deliveryarns or threads to bewound upon the splndles,

thread-guiding means such as guide-rails for guiding the yarns orthreads to the Specification of Letters Patent.

Fig. 28 is a side elevation of part of the mangle-wheel, showingthe .mechanism provided according to this invention are illustrated asapplied in a machine which in its general construction and mode ofoperation closely resembles that described in the specification of theLetters Patent granted to Herbert Leander Pratt and Charles ThomasUpton, Number 57 3,288, dated December 15th 1896.

a a are spindle-rails, eight being shown, supporting any requisitenumber of spindles 6 shown as spindles of the kind described in thespecification of the aforesaid Letters Patent, Number 996,580. Thespindle-rails a are secured at their ends to end-frames a which withrods (Z to connect them constitute the framework by which the otherparts of the machine are carried. The end-frames 0 which are providedwith holes in appropriate positions are furnished with hearingbracketswith caps in which are mounted the shafts of tin-rollers, four beingshown, which are made to impart motion to the pulleys of the spindles Z)by means of bands passed around the pulleys of the spindles Z) and oneor other of the tin-rollers e. The shaft of one of the tin-rollers e isprovided with a fast pulley f so that it may be driven and a loosepulley g and an intermediate pulley it by means of which the machine maybe driven at a slow speed and motion is transmitted from that shaft tothe shafts of the other tin-rollers e by means of sprocketwheels 1' andchains 9' mounted upon thetinroller-shafts.

The shaft of one of the tin-rollersw is furnished with a sprocket-wheelfast upon it around which ispassed a chain Z passing around asprocket-wheel m mounted fast upon the axle projecting atone end of oneof a group of three delivery-rollers n 0 39 mounted to revolve inbearings provided at the upper parts of the end-frames 0 and, atighteningpulley Q mounted upon a pivot carried by an arm pivoted to theone endframe 0 is provided to bear against and so to keep as tight asneed be the chain Z. The lower two delivery-rollers n 0 are supported bythe bearings in which they are respectively mounted and the third, p, issupported by the other two while being guided in its movement by thehearings in which it is mounted. A frame or cover if of glass panelsmounted in a suitable frame is provided to extend over all the spindlesb to protect the yarn or thread wound on to the spindles b from anyobjectionable matter falling from above it. For each rank of spindles bmounted in the spindle-rails a there is provided a guide-rod s. Theguide-rods s are shown as made'to extend lengthwise of the machinethrough holes in downwardly inclined arms 25 formed upon inclined bars afurnished with sockets to receive the upper ends of lifting devicesshown as consisting in poker-bars or lifter-pillars a: to which they aresecured as by nuts. The guide-rods s at their ends carry brackets inwhich they are secured by set-screws and which are secured by bolts toinclined bars w serving to prevent the guide-rods s from turning in thebars u o. The guide-rods s are provided with curls or eyes 00. It isconvenient that the curls or eyes 00 be inserted in collars secured byset-screws to the guide-rods s and placed together in pairs in orderthat yarns or threads may be led in divergent lines from adjacent curlsor eyes w to adjacent spindles b as is convenient.

As thus far described in detail the mechanism is very similar to thatdescribed in the specification of the aforesaid Letters Patent Number573,288 and the present invention consists in great part in themechanism next to be described for imparting the movement to theguide-rods 8 though there is much possibility of variation in the manner in which the poker-bars or lifter pillars c or any other deviceswhich may be used as equivalents therefor are guided and made to receivemotion from the parts with which this invention is more particularlyconcerned.

The poker-bars or lifter-pillars c are shown as made to pass throughholes formed in two of the spindle-rails s so as to be guided therebyand are shown as guided at their lower ends by fixed rails 42 verticallybelow the said two spindle-rails s and formed with racks in engagementwith pinions each mounted on one or other of two shafts 1 2 mounted tobe turned in bearings formed in the end-frames 0. Each shaft y 2 isshown as having a toothed wheel 1 fast upon it and a rack 2 in gear withthe two toothed wheels 1 shown mounted to be slid in guide-brackets 3upon the one endframe 0 so that-the two shaft-s 3 a shall always turnalike.

As best shown in Fig. 7 a pinion 4 upon the sh aft 1 and provided with.a notch is normally pressed by a spring 4 into engagement with a collart having a projection and fast upon the shaft 2 which is provided with ahandle y usually removed when not in actual use. Into the pinion 4engages a rack 5 shown as mounted to slide against the lower surface ofa bar shown as formed with a rack 6 in gear with a pinion 7 fast upon asleeve 7 mounted on a fixed stud 8. A mangle-wheel 9 is fastened on thesleeve 7 A projection 10 upon the rack 5 is provided to limit along witha shoulder upon the rack 6 the movement of the rack 5 in one directionrelatively to the rack 6. The rack 6 is shown as guided and kept in gearwith the pinion 7 and also guided laterally by means of projecting arms11 upon brackets secured to the one end-frame 0 one of which also servesto guide the rack 5 and to keep it in gear with the pinion 4. The rack 5is also made to rest upon and gear with a pinion 12 which is mounted tobe turned upon a stud 13 carried by the rack 6 and is fast with achainbarrel 14 to which one end of a chain 15 is connected. The chain 15is connected at its other end to a lever 16 mounted to swing upon a stud17 shown as carried by a frame 18 bolted at its upper and lower parts tothe one end-frame c. The lever 16 is shown as formed with a slot so thatthe stud connecting the chain 15 to it and adapted to be secured inposition by a nut maybe adjusted in position. The lever 16 is also shownas provided with a block 19 adjustable upon it and adapted to be securedin position by means of a bolt passed through a slot in the lever 16 andprovided with a nut and the block 19 is shown as formed with aprojecting arm or nose 19 to bear against the edge of a cam 20 shown asbeing more or less of spiral form and, with a ratchet-wheel 21, fast toit, mounted loose upon a stud 22 secured in the frame 18. The projectingarm or nose 19 is made to extend laterally from the lever 16 so that thelever 16 may pass by one side of the cam 20 while the projecting arm ornose 19 bears against the edge of the parts of smaller radius. The stud22 forms a pivot for an arm 23 which is weighted and carries a pawl 23to engage with the ratchet-wheel 21 and is shown as connected by aslotted link 24 shown as allowing lost motion to a stud 25 adjustableand fixed in position in a slot formed in the rack 6. A stud fixed inthe end-frame carries a weighted pawl 26 to which is connected one endof a spring 27 connected at its other end to a hook secured in the frame18, the pawl 26 serving to prevent the ratchet-wheel 21 from beingturned in the direction opposite to that in which it is turned by thepawl 23 carried by the arm 23 and also to prevent such ratchet-wheel 21from being turned in advance of the action of the pawl by the pressureexerted against the cam 20 by the lever 16. A stop screw 35 adjustablein a fixed bracket is provided to limit the movement of the arm 23 inone direction. On the shaft of one of the tin-rollers e a toothed wheel28 is mounted which gears into a toothed wheel 29 mounted loose upon astud 30 which is secured in the one end-frame 0 and forms the pivot of alever 31 shown as formed in two parts bolted together so that its lengthmay be adjusted. The lever 31 is provided with a bearing in which ashort shaft 32 is fitted to be revolved. The shaft 32 is provided with atoothed wheel 33 fast upon it and in gear with the toothed wheel 29 andwith a toothed pinion 34 fast upon it and in gear with the mangle-wheel9.

As is more clearly shown by Figs. 24, 25, 26, 27, 28, 29, and 30, themangle-wheel 9, as is usual with such things, is provided with a seriesof teeth 52 extending around the greater part but not all of itscircumference. In the gap between the ends of the series of teeth 52, isprovided a guide 53 shown as secured in position in the manglewheel 9 bymeans of bolts, collars and nuts and formed at opposite ends withhollows 54; 55, to be entered by and to guide the shaft 32 so that thepinion 34, working along the outer or inner side of the series of teeth52 of the mangle-wheel 9, will pass from time to time first into onehollow 54 and then into the other hollow 55 of the guide 53, so as to beheld by the guide 53 in gear with the tooth at the end of the serieswhile moving around such tooth from the outer to the inner side of themangle wheel 9 or from the inner to the outer side thereof as the casemay be.

In order to limit the movement of the lever 31 about the stud 30 and toprevent the pinion 34 from passing out of gear with the manglewheel 9 inits movement in either direction a bracket 36 secured by bolts to theone end-frame 0 is provided with two fingers extending so that the lever31 is between them.

Each of the spindles Z one of which is shown separately in Figs. 13 and14 comprises a bolster 37 with a foot-step 38, an inner bearing 39 andan outer bearing 40, a carrying part 41, in the form of a spindlebladearranged to revolve within the bolster 37, a driving part shown in theform of a pulley 42 and revolubly supported on the outer bearing 40 andshown as provided with a central projection 43, a frictional pad 44carried on the driving part 42 and around the central projection 43 anda frictiontransmitting device 45 in driving connection with the saidcarrying part 41 and movable in the direction of the length thereof andbearing on the frictional pad 44 and shown as provided with a centralrecess to receive the central projection 43. The carrying part 41 of thespindle Z) is shown as provided with a peg 46 to enter a correspondingrecess in each bobbin 47 to be applied to the spindle so that the bobbin47 in use is in rigid connection with such carrying part 41 so as alwaysto move therewith through the friction of the pad 44 against the drivingpart 42 and the friction-transmitting device 45 which remainsapproximately constant being unaffected by the weight of the carryingpart 41 and the bobbin 47 and yarn or thread carried by it. The bobbin47 and carrying part 41 are thus enabled easily to be held back by theyarn or thread so as to revolve at a speed corresponding to the rate atwhich yarns or threads are delivered by the rollers a 0 p although thedriving parts 42 are revolved at a speed higher than the speed requisitefor the carrying parts 41 when yarns or threads are being wound upon theparts of the bobbins 47 which are of least diameter.

In the ordinary working of the machine motion being imparted by the fastpulley to the shaft of the tin-roller e which carries the pulleys f g h,the tin-rollers being made to revolve will transmit, by means of bands48, motion to the spindles 7) while the shaft of the one tin-roller 0will transmit 'motion by means of the sprocket-wheel 70, chain Z andsprocket-wheel m to the delivery-roller a and thereby to the rollers 079 so that yarns or threads to be wound being delivered in anyappropriate way to the delivery-rollers n 0 p from any body or form onor into which they may have been wound already will all be delivered bysuch rollers n 0 p at a similar rate to the spindles b. The spindles Dare driven so as to tend always to wind yarns or threads at a speedgreater than that at which they are delivered by means of thedelivery-rollers n 0 72 and consequently the bobbins 47 or the like onthe spindles Z) which receive the yarns or threads revolve a little moreslowly than the driving parts 42 of the spindles?) and the more so asthe quantity of yarns or threads wound upon each of the bobbins or thelike increases in diameter. As the spindles I) revolve, motion is alsotransmitted from the shaft of the one tinroller e by means of thetoothed wheel 28, toothed wheels 29 and 33,

shaft 32 to the pinion 34 which is made to revolve and thus to act uponthe teeth of the mangle-wheel 9. If the pinion 34 be in gear with theouter side of the series of teeth 52 of the mangle-wheel 9, as shown inFigs. 1,

2, 11, 24 and 25, it will turn such manglewheel 9 in one direction untilthe pinion 34, passing int-o gear with the tooth at the one end of theseries brings the shaft 32 into the hollow 54 at the one end of theguide 53 and is thereby compelled to work around the tooth in the mannerillustrated by Fig. 26, to the inner side of the series of teeth 52 andthen the pinion 34 working along the inner side of the series of teeth52, as shown in Fig. 27, will turn the mangle-wheel 9 in the oppositedirection until it arrives at the tooth at the other end of the seriesand bringing the shaft 32 into the hollow 55 at the other end of theguide 53, is guided around such tooth to the outer side of the series ofteeth 52. The mangle-wheel 9 is thus made toturn alternately in oppositedirect-ions and to move the rack 6'forward and backward and thereby ifthe projection 10 be against the shoulder of the rack 6 to move the rack5 backward and to allow it to be moved forward so that the guide-rods 8being made to receive motion from the rack 5 through the pinion 4,shafts 3 z and poker-bars or lifter-pillars 1) will be raised andlowered through a distance corresponding to the movement forward andbackward of the rack 6. v a

In the backward movement of the rack 6 the slotted link 24 is moved bythe stud 25 so as to turn the lever 23 in the direction opposite to thatin which its weight tends to turn it and as the rack 6 moves forward thestud 25 is withdrawn and first pulls and then after a certain positionis attained allows the lever 23 to be turned by its weight. Theratchet-wheel 21 is thus gradually turned by the pawl 23 and therebymade to turn the cam 20 so as gradually to present to the nose 19 a partof larger and larger radius until the apex of the cam 20 is presented toor moved past the nose 19 and then to present to the nose 19 either thepart of least radius or other part more or less adjacent thereto and soon. hen the cam 20 is made to present the part of least radius to thenose 19 of the block 19 the projection 10 of the rack 5 is against theshoulder of the rack 6 throughout the forward and backward movement sothat the movement upward and downward of the guide-rods 8 corresponds tothe movement of therack 6. As gradually the cam 20 is made to present tothe nose 19 a part of larger and larger radius the chain 15 is tightenedso as to begin to turn the barrel l4 earlier and earlier in the backwardmovement of the rack 6 and thus to cause the pinion 12 to move the rack5 backward rela tively to the rack 6 to a greater and greater extent inthe successive backward move- 'ments thereof thereby causing a greaterand greater movement of the rack 5 and thereby a greater and greatermovement of the guide-rods 8 until the movement begins again as amovement of smaller extent. It isordinarily convenient that the cam 20should be turned at such a rate that the change from minimum to maximummovement of the guide-rods 8 should take place in about seven or eightascents of the guide rods 8. Obviously the upward movement of theguide-rods s in the ordinary course of the winding of yarn in themachine takes place always from one position and then gradually extendsin successive upward movements nearer to the top of the bobbin or thelike until the maximum movement in each increase is attained andconsequently the yarns or threads are wound into a body tapering upwardmore or less in the form of a tapering bottle which enables, as is wellknown, the yarns or threads to .be pulled 0E easily at the end withoutrequiring the bobbin 17 or the like or the mass of yarn thereon itselfto turn, this being of especial advantage for the unwinding withoutdanger of breakage of fine or weak yarns or threads. Obviouslyadjustment of the position of the stud 25 of the pawl 23 or of thestop-screw 35 or change of the ratchet-wheel 21 or two or more of theseexpedients will enable the rate of change in the movement of theguide-rods s easily to be adjusted and by the various toothed wheels andpinions employed being changed for others of different relativeproportions any requisite or desirable relations between the rates ofmovement of the several parts of the machine may be obtained. I

If the cam 20 be made to present its part of least radius to the nose 19and the pawl 23 be then turned out of position to act upon theratchet-wheel 21, the racks 5, 6 will continue to move alike and theguiderods 8 will move up and down always between the same limits for anindefinite period so that the machine may be used for winding yarns orthreads on bobbins or the like with flanges at both ends.

WVhen the bobbins in use upon the spindles have been filled with yarn orthread the guide-rods s are lowered'by means of the disengagement of thepinion 4: from the collar 1* and the use of the handle y so that a fewturns of yarn or thread are wound upon the braids of the spindles b andthe filled bobbins 47 being removed from the spindles Z), fresh bobbins4:7 are placed thereon and the guide-rods s" are raised again by meansof the handle y and the pinion 4 is then allowed to pass again intoengagement with the collar 4 and the yarns or threads being alreadyattached to the braids of the spindles b begin to be wound upon thebobbins 47.

Bobbins with the lower surfaces of the flanges at the lower ends in thesame plane as the braids of the spindles Z) to which they are applied orin planes nearer to the tips of the spindles may be used but there is inthe use of such bobbins some risk thatyarns or threads in being guideddownward with the object of being wound upon the spindlebraids or beingguided upward after being wound upon the spindle-braids in order to bewound on to newly applied bobbins may pass into the gaps between theflanges of the bobbins and the spindle-braids and thus be wound on tothe blades of the spindles with the result that it may be difficult toguide them in the way desired and that eventually there may beobstruction by the yarn or thread wound upon the spindleblades to theapplication ofbobbins upon the spindle-blades. In order to obviate thisinconvenience, it is preferable to use bobbins provided with lowerflanges formed with recesses adapted to cover the braids of the spindlesor like parts wholly or partially to such an extent as to prevent yarnsor threads from passing between the flanges and the braids or likeparts. Flanges formed in this way are shown in Figs. 15, 16, 17 21, 22and 23 which show recesses 19 formed in the flanges 50 so that theflanges 50 eX- tend some little way down the braids so as to guide yarnor thread safely on to the collars below the braids of the spindles b.

In order to insure that in the commence ment of winding upon bobbinsyarns or threads led on to bobbins after being led to the spindles so asto be wound upon the braids or collars thereof shall commence at once tobe wound upon the bobbins when the spindles are set in motion after astoppage for the placing of fresh bobbins upon the spindles andespecially when as usual they move slowly in being set in motion aftersuch .a stoppage notches or indentations 51 are formed in the flanges 50or like parts of bobbins so that the yarns or threads may be caught andengaged therein and so at once begin to be wound upon the bobbins. Theremay be one notch or indentation or a greater number of notches orindentations, Figs. 18, 19, 2O showlng a flange with one and Figs 15,16,17 showing a flange with four. Figs. 15, 16, 17 show notches orindentations formed in flanges formed with recesses 49 and Figs. 18, 19,20 illustratethe formation of notches or indentations formed in flangeswithout such recesses 19. Figs. 15, 16, 17, 1s, 19, 20, 21, 22 and 23show bobbins with wide flanges at one end such as are used in windingyarns or threads into forms tapering at one end.
